Product Overview
Spin-On filters are among the most widely used and reliable filtration solutions in the automotive, construction, agricultural and industrial equipment sectors. With their integrated design — cartridge and metal canister in one assembly — they allow fast, safe installation and can be replaced without opening a separate housing. Compact construction, reliable sealing and consistent performance have made Spin-On filters the standard choice across lubrication, fuel and hydraulic systems.
Design and Construction Features
Applications
Spin-On filters are used across a wide range of systems:
Product Categories
Engine Oil Filters (Spin-On Oil Filters)
Application: Lubrication systems of light and heavy petrol and diesel engines.
Functional Goal: Removal of wear particles, soot and oxidation products to extend bearing and moving-surface life.
- Separation efficiency up to 99% at the defined particle size
- Bypass valve calibrated to the engine design pressure
- Anti-drain back valve to prevent dry start
- High dirt-holding capacity for extended service intervals
As per engine application
Full engine operating temperature range
Fuel Filters (Spin-On Fuel Filters)
Application: Light and heavy diesel engines, construction equipment and generators.
Functional Goal: Removal of suspended particles and protection of pumps and sensitive injectors.
- Precision micron-rated media with high efficiency for fine particles
- Controlled pressure drop to maintain fuel flow rate
- Compatible with low-sulphur diesel and biodiesel fuels (subject to material selection)
Micron Rating
Per application
Per fuel type
Fuel Water Separator (Spin-On Fuel Water Separator)
Application: Diesel systems in humid conditions or where fuel has a high risk of water contamination.
Functional Goal: Separation of free and emulsified water from fuel to prevent corrosion, cavitation and injector damage.
- Coalescing media to agglomerate fine water droplets
- Lower bowl — metal or transparent — for water inspection and drainage
- Manual drain valve or water-in-fuel sensor alert (advanced models)
- Extended injection system service life
- Reduced failures caused by rust and microbial growth
- Combines particulate filtration and water separation in a single unit
Hydraulic Filters (Spin-On Hydraulic Filters)
Application: Return lines, medium or low-pressure circuits in industrial hydraulic systems and heavy machinery.
Functional Goal: Control of hydraulic oil contamination level to the target cleanliness class (ISO 4406).
- Synthetic media with high Beta Ratio βx ≥ 200 at the specified particle size
- Designed to withstand sudden pressure pulses
- Available with or without internal bypass depending on circuit design
